they don't all work the same. but i'd stay away from them. it can hurt your credit even more. there are simple things you can do on your own that work basically the same, except you aren't paying them for their 'help'. i can post details here or you can email me. (or im)
Hmm if you want you can post details here so that others can be helped in case they have this question. Or if you want just send it to my Ezabel inbox. Whatever works.
